Charlie Grainger (6.5) – Tough day for the goalkeeper, although he couldn’t do much about all three goals. He made one decent save from a free kick and a great stop before the second, but despite the scoreline had very little to do.

Myles Judd (5.5) – Difficult afternoon for the full-back, but he wasn’t protected enough by his team-mates. He allowed Danny Andrews too much space for the opener and found it tough, especially against Grimsby substitute Akwasi Asante. A learning curve for the 18-year-old.

Nicky Hunt (6) – Nowhere to be seen for the Mariners second and should have done better for the third, but made a fine tackle to keep it 1-0 soon after the break and is playing out of position.

Tom Parkes (6) – Like the rest of the back-four he struggled against the visitors pacey attacking line-up and was caught up the pitch on a couple of occasions, but probably still isn’t fully fit.

Callum Kennedy (5.5) – Left-back is playing with groin problem and had more injury issues throughout. He should’ve done better for the opener and then was unfortunate to see the ball rebound off him and in to give Grimsby a second, but nearly pulled one back late on, as his long range effort hit the post, though it wasn’t to be.

Steven Alzate (6.5) – Youngster is supremely talented and demonstrated his ability and quick feet on numerous occasions on Saturday, but he didn’t help Judd enough. He should have backed up his team-mate more for the second, although it is only his third senior appearance.

Freddy Moncur (7.5) – The 20-year-old was arguably the best player on the pitch in the first half and won the ball back so many times. He buzzed around brilliantly and looked neat in possession and always provided an option for his team-mates. He is taking his overdue opportunity.

Michael Collins (7) – Similar to Moncur, he was impressive during the first 45 and pushed to get Orient back in the game, but his set-pieces weren’t great and he could have done better for Grimsby’s third goal. Nevertheless, carried on battling until the full time whistle.

Sandro Semedo (6.5) – Portuguese winger got plenty of joy against his full-back, but his final product wasn’t good enough considering the O’s options up front. His balls into the area needed to be low and hard rather than high, but it was another decent display.

Josh Koroma (6.5) – After hitting a hat-trick against Newport County, the 18-year-old found life tougher on Saturday, but nearly found the back of the net. He went close on a few occasions after the break and always looked lively.

Sam Dalby (5.5) – Tough day for the teen, but let’s not forget 18-months ago he was playing for Buckhurst Hill boys and now he is up against experienced defenders. He should stay up front more, but is only 17 and when he does drop deep and get on the ball, he oozes class. Dalby is immensely talented, but could do with an experienced partner up top.

Substitutes:

Tristan Abrahams, for Dalby 69. (6) – A decent chance to impress with 20 minutes to go at Brisbane Road, but Grimsby doubled their lead just after his introduction. He tried to get on the ball and use his physical presence to unsettle the visitors, but the game was virtually over.
